TOOL.

To all whom it may concern:

Be it known that I, EARLJ. GRIosBY, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Tools of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved tool and more particularly to a tool for applying and removing shade roller brackets.

It is a more particular object of my 1nvention to provide a tool particularly designed for use in applying and removlnga shade roller bracket of rectangular loopshaped form, such as that described and claimed in my copending appl1cat1on for patent, Serial No. 228,4l05, filed Aprll 13, 1918, said tool also being provided with means whereby the rectangular spring winding trunnion of a shade roller may be rotated and with additional means for applying or removing the flat type of roller bracket.

And it is a further general object of the invention to provide a tool for the above purpose, which is of very simple construction, highly serviceable and convenlent for the purpose in View, and which can be manufactured at relatively small cost.

With the above and other objects in view, the invention consists in the improved form of construction and arrangement of the several parts as will be hereinafter more particularly described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate corresponding parts throughout the several views, and wherein Figure 1 is a longitudinal sectional view illustrating the preferred construction of my improved tool;

Fig. 2 is a section through the tool head taken on the line 22 of Fig. 1 showing the head of the tool applied to a loop-shaped shade roller bracket;

Fig. 3 is a section taken at right angles to Fig. 2; and showing the tool head applied to a flat bracket plate; and

Fig. 4 is an enlarged perspective view of the tool head.

Referring in detail to the drawing, 5 designates the shank of the tool wh1ch may be either of rectangular or cylindrical form, and to this tool shank adjacent one of its -ends, one section 6 of a hollow handle is Specification of Letters Patent.

suitably secured. The other section 7 of the handle has detachable threaded connection with the handle section 6. When the two handle sections are connected, they form a substantially elliptical-shaped hand grasp whereby the too-l may be conveniently manipulated. VVit-hin the hollow handle, wood punches, screw driving bits and like tool ele ments may be contained.

The opposite end of the tool shank 5 is formed with a rectangular head 8 and at the opposite sides of this tool head, longitudinally projecting flanges 9 are provided. In the accompanying drawing I have illustrated a loop-shaped sheet metal bracket member B similar to the bracket shown and described in my co-pending application hereinbefore referred to, said bracket member being provided at one side with an attaching screw adapted to be threaded into the window frame. In applying or removing this loopshaped bracket, the bracket plate is engaged against the tool head 8 between the flanges 9 thereon. The tool is then turned or rotated to cause the attaching screw to thread into the window frame or to remove the attach ing screw therefrom.

In addition to the flanges 9 the tool head 8 is centrally provided with a rectangular longitudinally extending socket 10 and in the opposite side walls of this socket the grooves or kerfs 11 are formed. The socket 10 is adapted to receive the rectangular trunnion of a shade roller when it is necessary to turn the trunnion in order to properly tension the roller spring. The kerfs 11 in the tool head are adapted to receive the opposite longitudinal edges of a flat metal bracket plate indicated at D, said bracket plate having an attaching screw formed on one of its ends. Thus, it will be seen that my improved tool can be used for applying or removing either form of a shade roller bracket.

The socket 10 is also designed to receive the rectangular end of a suitable wood punch whereby the hole may be formed in the face of the window frame so that the bracketattaching screw can be readily started and the tool head then subsequently applied to the bracket to thread the screw tightly in the frame. Screw driving bits and other tools may also be engaged in the socket 10 of the tool head whereby they may. be conveniently turned or rotated.

In addition to the above noted features of my improved tool, I also preferably provide one of the flanges 9 on the tool head with a central notch indicated at l2 so that this flange can be conveniently employed for the purpose of extracting tacks, nails and analogous fastening elements.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have produced a highly serviceable and convenient tool, which can be produced at small manufacturing cost and is well adapted for the application or removal of shade roller brackets of the several types hereinbefore referred to. The tool can of course be constructed in many different sizes and while I have herein shown and described the preferred form or construction and arrangement of the several parts it is to be understood that the same are susceptible of considerable modification and I therefore reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim o The herein described tool for removing and applying shade roller brackets comprising a shank having an enlarged rectangular head on one end formed with a rectangular axially extending socket opening upon the end face of said head and provided with longitudinal kerfs in the opposed walls of said socket adapted to receive a fiat metal bracket plate, said head being also formed at opposite sides thereof with longitudinally projecting flanges adaptedto receive between them a loop-shaped bracket member.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
